</li><li> Tables and summary reports in https://bugzilla.mozilla.org/show_bug.cgi?id=708406

</li><li> Written report and summary tables are attached to the ticket.  

</li><li> Summary file, in CSV format, is 620MB compressed, 7.2GB uncompressed, available at http://analysis.net/moz/css.csv.gz

<h4> Q&amp;A </h4>

<ul><li> how many sites in your mobile Webkit browser crawl use at least one of 'transition', 'transition-timing-function', 'transition-duration', 'transition-property', 'transition-delay' (ignoring prefixes)?

<p>1245 / 30087 = 4.13%

<ul><li> how many use them only with -webkit prefixes (no -moz or unprefixed versions of the properties)?

<p>336 / 30087 = 1.12%

<ul><li> how many use them only with -webkit prefixes and unprefixed (no -moz versions of the properties)?

<p>365 / 30087 = 1.21%

<ul><li> For each CSS prefix for which there are both -moz- and -webkit- prefixes, what percentage of domains host CSS that uses only the -webkit- version and not the -moz- or unprefixed version?
